The identity of each body segment in Drosophila is determined by the products of genes in which of the following complexes?
A) Bithorax
B) Antennapedia
C) Femurtibia
D) Bithorax and antennapedia
E) Antennapedia and femurtibia

Question

Quizplus · Accepted Answer

The bithorax and antennapedia complexes contain genes that determine the identity of body segments in Drosophila. The bithorax complex is responsible for specifying the identity of the second and third thoracic segments, while the antennapedia complex controls the identity of the head and first thoracic segments. Therefore, the correct answer is D - bithorax and antennapedia complexes. Femurtibia is not a known complex that determines body segment identity in Drosophila.
